OLDCB	QoS on RTP 01 Key: OLDCB.GLOBAL.TOS.ENABLE Description: Enable QoS on the RTP stream. Constraint: 0 for disable 1 for enable Related settings: QoS value on RTP (OLDCB.GLOBAL.TOS.VALUE) QoS value on SIP (application.qos.signalling.diffserv) QoS value on video call RTP stream (OLDCB.GLOBAL.VIDEO.TOS.VALUE)

The default  value 184 in decimal (10111000 in binary format) for this whole byte.

That means that DSCP field is set to 0x2E (46 in decimal) and CU field is set to 0.

If administrators need to change it, just follow this small procedure

1.Get the DSCP field value from the network infrastructure manager ;

2.Connect to the TSS administration console from your preferred Internet navigator and log onto the system with administration privileges ;

3.From the main menu, navigate to the Device Management | Zones and click on your zone

4.Go to the TPO Boot Settings and OLDCB | Expert Mode panel

5.Set the QoS Value for voice call

Location: TPO Boot Settings
OLDCB	QoS value on RTP Key: OLDCB.GLOBAL.TOS.VALUE Description: This parameter enables and set the DiffServ value. The 8 bits of DiffServ field are as follow: 0 1 2 3 4 5 6 7 +---+---+---+---+---+---+---+---+ | DSCP | CU | +---+---+---+---+---+---+---+---+ By Default, the feature is enabled and set value 184(101110)for this whole byte. That means that DSCP field is set to 0x2E(46 in decimal) and gives a value of EF The default value aligns with RFC 4594 https://datatracker.ietf.org/doc/html/rfc4594 ------------------------------------------------------- | Service | DSCP | DSCP | Application | | Class Name | Name | Value | Examples | |===============+=========+=============+| | Telephony | EF | 101110 | IP Telephony bearer | Constraint: The value must be between 0 to 255. Related settings: QoS on RTP (OLDCB.GLOBAL.TOS.ENABLE) QoS value on SIP (application.qos.signalling.diffserv)

6.Set the Qos Value for video call

Location: TPO Boot Settings
OLDCB	QoS value on video call RTP stream Key: OLDCB.GLOBAL.VIDEO.TOS.VALUE Description: Define the value of QoS which included DSCP and CU. If this setting is not set, the video QoS value given by OLDCB.GLOBAL.TOS.VALUE (184 by default) The value 184 in decimal means the value of DSCP is 46 (0x2E). Constraint: The value must be between 0 to 255. Related settings: QoS on RTP (OLDCB.GLOBAL.TOS.ENABLE) QoS value on SIP (application.qos.signalling.diffserv)

•QoS on SIP

The default value is -1 which means disable.

To enable it:

1.Connect to the TSS administration console from your preferred Internet navigator and log onto the system with administration privileges ;

2.From the main menu, navigate to the Device Management | Zones and click on your zone

3.Go to the TPO Boot Settings and SIP | Expert Mode panel

4.Set the value (example 184);

Location: TPO Shared Settings, TPO Private Settings, TPO Boot Settings
SIP	QoS value on SIP Key: application.qos.signalling.diffserv Description: This parameter enables and set the DiffServ value. The 8 bits of DiffServ field are as follow: 0 1 2 3 4 5 6 7 +---+---+---+---+---+---+---+---+ | DSCP | CU | +---+---+---+---+---+---+---+---+ By Default, the feature is enabled and set value 160(101000)for this whole byte. That means that DSCP field is set to 0x28(40 in decimal) and gives a value of CS5 The default value aligns with RFC 4594 https://datatracker.ietf.org/doc/html/rfc4594 ------------------------------------------------------- | Service | DSCP | DSCP | Application | | Class Name | Name | Value | Examples | |===============+=========+=============+| | Signaling | CS5 | 101000 | IP Telephony signaling | |---------------+---------+-------------+------------| Constraint: value must be in the range -1 to 255. -1 means disable Related settings: QoS on RTP (OLDCB.GLOBAL.TOS.ENABLE) QoS value on RTP (OLDCB.GLOBAL.TOS.VALUE) QoS value on video call RTP stream (OLDCB.GLOBAL.VIDEO.TOS.VALUE)
